NREL and iUnit Open the Door to Grid-Integrated, Multifamily Construction

May 11, 2017

NREL showcased one of its newest capabilities at the Energy Systems Integration Facility
(ESIF) on May 4. Nearly 30 industry partners, representing 25 companies, visited a
380-square-foot modular studio prototype apartment created by Denver developer, iUnit.
Open house participants were able to tour the unit in person and learn about the partnership between iUnit and NREL, including the use of NREL’s apartment-in-the-loop research capabilities and energy
modeling tools.

The draw for learning about the iUnit is multipronged:

Growing Multifamily Housing Needs: Roughly 38 million people in the United States live in buildings that contain five
or more units, totaling almost 18.5 million households, increasing the demand for
multifamily construction

Faster Construction, Occupancy: It’s much faster to build these modular multifamily residences as the modular construction
allows fully furnished units to be assembled and shipped to the site, ready to install,
leading to faster occupancy

The ESIF provides a unique contained and controlled platform where partners can identify
and resolve the technical, operational, and financial risks of integrating emerging
energy technologies into today’s energy system. While the iUnit team is focusing on
enhanced energy efficiency and creating a modular, zero energy apartment technology
development platform for construction, the team is also testing several new innovations
at the ESIF before incorporating them into their planned Champa Flats community in
Denver, which will include a microgrid system.
